What it is
LeCHECK is the contract review feature of Lisse Legal AI Cowork, which also lists legal drafting, research, translation, matter management, and contract management. Users can upload contracts for AI analysis that flags risky clauses and proposes revisions and comment drafts. Review can use a company’s criteria, templates, and past handling history, and compare a document with registered similar contracts or company templates to show differences. The review feature works as a Microsoft Word add-in. The maker describes the SaaS environment as accessed from a PC browser and lists Windows and macOS support, recommending current Chrome or Edge. Legal research draws on sources such as e-Gov and government agencies, with references shown alongside answers; the maker says research results connect with review and drafting. The legal-focused AI is supervised by more than 30 lawyers, according to the maker, while a human staff member makes the final legal decision on review results. The maker lists security measures including SSL/TLS 1.2 encryption, IP restrictions, WAF, and annual third-party vulnerability assessments, and clarifies its ISO certifications apply to organizational management systems. Pricing depends on account count and organizational structure and is available on request. The free trial requires no credit card and does not automatically charge at its end.
